[英]adding info window on click on marker in google map
我正在使用PHP和MYSQL,以便从数据库中检索数据并在Google Map API上显示标记,并添加一个信息窗口,其中包括使用click-Listener从数据库中检索到的信息。 在我添加了信息窗口后,它似乎没有用。
我的错误在哪里?

您必须在html标记中放入所需的弹出窗口。 以及Google Maps标签中的代码对其进行初始化。 并使用data-popupstring-id="#popupstring1"
标签在data-popupstring-id="#popupstring1"
标记时对其进行初始化。
var $popup = $("#popupstring1")
function addMarker(feature) {
var marker = new google.maps.Marker({
position: feature.position,
data-popupstring-id: $popup,
map: map
});
}
我通过添加以下代码解决了这个问题:
var popup = new google.maps.InfoWindow({
content: feature,
maxWidth: 300
});
google.maps.event.addListener(marker, "click", function() {
if (currentPopup != null) {
currentPopup.close();
currentPopup = null;
}
popup.open(map, marker);
currentPopup = popup;
});
google.maps.event.addListener(popup, "closeclick", function() {
map.panTo(center);
currentPopup = null;
});
